Am I finished?

So here's what I have been working on for my dad. It is huge (30" x 40"). For months, the white canvas just stayed wrapped up in the plastic, because I didn't know how to handle it. But I finally found the courage to bust open the plastic and add a little paint and paper. I really like how it has turned out, but I'm not sure whether it's finished. I was working on a large B&W print of my girls to hang in the top 3rd, but now I'm not liking how the photo turned out. The color isn't quite right and the words I've added don't have the same effect I was going for in my head. So now it's back to the drawing board. Or maybe it is finished. Maybe it has been finished. By adding a picture over top, my girls were going to become the art and my artwork was going to fade into the background. But by leaving it as is, I feel a bit exposed, like "Here I am. Here's my art." Hmm....
